What is the renewable energy? Renewable energy use energy sources that are continuously renewed their nature-Sun, wind, water, Earth heat, and plants. Renewable energy technologies turn this fuel to usable forms of energy often elec- tricity, but also the heat, chemicals, or mechanical energy. Why use a renewable energy? Today we are in the first place the use of fossil fuels to heat and power our homes and fuel our cars. It is convenient to use the coal, oil and natural gas, for a meeting of our energy needs, but we have a limited supply of this fuel on the ground. We use them so much more quickly than being created. Even- tually, they will run out. Because of safety concerns and waste disposal prob- lems, United States ??????? a lot of nuclear power by 2020. in mean- time, the nation’s needs energy is expected to grow by 33% over 20 years to come. Renewable energy can help fill the gap. Even if we had unlimited supply fos- sil fuel, using renewable energy best of the environment, and we often called renew- able energy technologies “clean” or “Green” because they are produces a little if any of pollutants. Burning fossil fuels, However, sends greenhouse gas in atmos- phere, trapping Sun and against tributing to global warming. Climate scientists generally agree to the Earth average temperature increased in the last century. If this trend continues, sea level will go up, and scientists is expected to flood, heat waves drought, and other extreme weather conditions can occur more often. Other pollutants are released in the air, soils, and water when fossil fuels are burning. This pollutants’s take a thrilling toll on the environment, and humans. Air pollution contribute to diseases such as asthma. Acid rain of sulfur dioxide nitrogen oxides hurt plants and fish. Nitrogen oxides also contribute to the smog. Renewable energy will also help the United States develop energy independence secu- rity. United States of imports more than 50 percent of the oil, an increase of 34 percent in 1973. replace some of our oil with fuel made of plant matter, for example, you can save money and strengthening our security of energy. Renewable energy plentiful, and technology is the improvement of all the time. There are many ways in renewable energy. Most of US are already use of renewable energy in our daily lives. Hydropower hydropower is our most mature and largest source of renewable energy, pro for ducing about 10 per cent of the country electricity. Existing hydroelectric power of about 77,000 megawatts (mw). Hydro- power plants energy conversion in flowing water to electricity. The most common form of hydropower uses the dam on the River to keep a large water tank. The water is released through turbines power generation. “Run of the River” systems how- ever, water diversion of the River directly through the pipeline to turbine. Hydropower plant production no air emis- sions, but can affect the water quality wildlife habitats. Therefore, hydropower plants are currently design oper- ated to minimize the impact on the River. Some of them converter is part of the flow around them dams on the tradition of natural flow of the River, but in spite of this improvement of wildlife in the River habitat, it is also reduces the power plant production. In addition, the fish lad- ders and other approaches, such as improving tur- bines, used to help the fish with a migration and reduce the number of fish kill. Bioenergy bioenergy are the energy-derived bio- block (organic matter), such as the plants. If you ever burn Wood in the fireplace or campfire, used bioenergy. But we do not get all of our biomass resources directly from the trees or other plants. Many industries like this post in against struction or processing of agricultural products, can create a large amounts of unused or the remaining biomass, which can serve as a bio-energy source. Biopower after hydropower, biomass is this coun- try to the second leading renewable energy resources, represents more than 7,000 mw installed capacity of some of the facilities and power generation and companies with coal power plants have found that replac- ING some coal with biomass is a low-option to reduce the unwanted emissions. As much as 15% of coal can be replaced biomass. Biomass has less sulfur of coal. Hence, fewer sulfur dioxide, contributing to the acid rain, is released in the air. In addition, using biomass in this boilers reduces oxide nitrous emissions. Process called gasification-on conver- Sion of biomass in gas, which is burning in turbine soft-another way to gener- eat electricity. Decay of biomass in landfills also gas production, most of them methane, which can burn in the boiler to produce a steam for generating electricity or industrial processes. Biomass can also heated in the absence of oxygen to chemically convert it to the type of fuel oil, called pyrolysis oil. Pyrolysis oil can be used to generate electricity as a result of feed- stock fuel, chemical and production.What is the renewable energy?
